Selectable Image Quality and Size
The SNC-CS3N provides the flexibility to select
image quality and image size according to
network bandwidth. Employing the industry-
standard JPEG-compression format, the
SNC-CS3N has a selectable compression ratio
within the range of 1/5 to 1/60. Also, the
image size can be selected from four modes:
736 x 480, 640 x 480, 320 x 240, and 160 x
120.
Backlight Compensation (BLC)
The Backlight Compensation (BLC) function
helps to overcome severe backlighting
situations, which often can cause the subject of
an image to be cast into a shadow. The image
brightness can be set to automatically
compensate for adverse lighting conditions.
Alarm Function
Activity Detection/Alarm Trigger
The SNC-CS3N is equipped with built-in activity
detection that can be set to generate an alarm
output through alarm-output ports. If a change
in luminance level is detected in the field of
view, an alarm is automatically triggered. In
addition, the SNC-CS3N is equipped with an
alarm-input port that can receive a trigger from
an external sensor.
Pre-/Post-Alarm Image Storage
With the built-in 8MB buffer, the SNC-CS3N
can store hundreds of pre-alarm and post-alarm
still images at the time an alarm is triggered
from the activity detection, the alarm input or
both.
Image Transfer using FTP/SMTP
The pre-/post-alarm images stored at the time
of an alarm event can be transferred to an FTP
server. A still image can also be sent as JPEG
attachments to a specified e-mail address,
enabling the user to see what happened when
an alarm occurred.
Versatile Interfaces
(Fig. 2)
Analog Composite Video Output
The SNC-CS3N has an analog composite video
output from the BNC connector located on its
rear panel. Like conventional analog cameras,
the SNC-CS3N allows the camera images to be
directly recorded or monitored by connecting
video equipment such as time-lapse recorders,
hard disk recorders, multiplexers, and monitors.
RS-232C Interface
The SNC-CS3N has a transparency function
available via the RS-232C interface. This allows
external equipment or sensors connected to the
RS-232C port of the SNC-CS3N network
camera to be controlled or monitored from the
PC over the network.
AC 24 V or DC 12 V Operation
The SNC-CS3N offers a choice of two power
supplies: AC 24 V or DC 12 V. The camera's
power system automatically adapts to the
supplied power.
